headcanon: i think dee dee and gina went to the same elementary school together.
so, i don't think they're friends (at least not in the books)
but when gina goes to ask for advice, instead of going to one of her pre-established friends, she's talking to dee dee.
outside of the more realest explanation that it would be easier to make the joke with two established characters, i think this happens because:
a. dee dee is connected enough to be on good terms with nearly everyone, including gina.
b. the two of them don't typically hang out, but know the other well enough just by being acquaintances for that long. and this usually comes with growing up together. which would explain why gina is more willing to go to her first rather than the other way around.
